Title: Digital transmission system for pair cable
Inventor: KAMEYAMA SHIGEJI
IPC: H04L7/00
Filed: 1986-07-31
Abstract: PURPOSE:To perform correct decoding regardless of whether or not pulse polarity inversion is caused on a transmission medium by generating a control signal indicating whether or not the polarity inversion is caused on a transmission line according to which of a 1st and a 2nd frame synchronizing circuit performs frame. CONSTITUTION:A switching controller 9 detects whether or not the pulse polarity is inverted on the transmission line including a cable 10 after the convergence of an equalizer 2 according to which of the frame synchronizing circuits 7 and 8 a pulse indicating synchronization attainment arrives from. The connection state of a polarity switch is so set that when the inversion is not cause (or caused), the sent pulse train of the discriminator 3 (or 4) is led to the positive polarity pulse input terminal of a decoder 6 and the sent pulse train of the discriminator 4 (or 3) is led to the negative pulse input terminal of the decoder 6. Then, the training and frame synchronization of the equalizer 2 are performed in a training period and the pulse polarity inversion on the transmission line is detected; when there is the inversion, the polarity is inverted again by the polarity switch 5.

Title: Tablet input device
Inventor: SAITO MINORU
IPC: G06F3/041
Filed: 1984-08-31
Abstract: PURPOSE:To specify the positions of contacts with a small number of scan frequency by setting the 1st and 2nd electrode lines to a tablet alternately in the prescribed number of pieces at the same interval as the segments and detecting the pulses scanned successively by means of a detection means having a contact with the tablet. CONSTITUTION:When a detection pen 12 has a contact with a tablet 11, a pen switch 13 works. A CPU first connects an MPX to a decoder DX1 with supply of a signal PSW and then the address signal AD which varies successively between 0 and 3 at a fixed time interval. Thus the DX1 detects the pulses which scanned successively the line groups 3-6 with the pen 12. These pulses are converted into the digital value accordant with the pulse height by the AD and stored in the prescribed address of a RAM. The CPU extracts the maximum one of signals S3-S6 corresponding to the scans of the 1st line groups 3-6 and and then the maximum and the next maximum ones of signals S7-S9 corresponding to the scans of the 2nd line groups 7-9 to discriminate that the pen 12 has a contact with the level close to the next maximum signal. Then the CPU sends the data TD showing contact areas of X and Y directions to a data processor, etc. via an IO.

Title: Knocking control device for internal combustion engine
Inventor: KANO KOICHI
IPC: F02D45/00
Filed: 1990-07-12
Abstract: PURPOSE:To secure desirable knocking control performance by providing a background level correcting means for correcting the background level according to the change rates of engine speed and engine load. CONSTITUTION:During transient operation, the response delay of BGL (background level) becomes larger as the change rates of engine speed and engine load become larger. The BGL is therefore corrected by a correcting means accordingly, that is, in the positive direction at the time of acceleration and in the negative direction at the time of deceleration. In a knocking judging means, the reference value obtained by adding the corrected BGL to the slice level is compared to the detection value of engine vibration detected by a detecting means to judge knocking. As a result, the knocking judging accuracy even during transient operation can be as high as during steady operation.

Abstract: PROBLEM TO BE SOLVED: To prevent a vehicle from being traveled inadvertently by supporting the tips of operation wires with a support section laterally moved interlockingly with a shift operation lever to shift the right and left HST devices, rockably connecting guide bodies to an operation handle, and expanding/shrinking the operation wires to the deceleration side for steering when a machine body is turned. SOLUTION: Guide bodies 26, 26' provided on the surface and back face of a substrate 7 are symmetrically arranged to cross each other at the neutral support position, and operation wires 6, 6' are invariably extended/shrunk by the same length. When a shift operation lever is operated, a rotating main shift guide 24 laterally moves a support member 10 along a guide groove 16, and the operation wires 6, 6' supported on the support member 10 are extended/ shrunk along the inclined guide bodies 26, 26' and can be displaced from the forward highest speed position at one end of the guide bodies 26, 26' to the reverse highest speed position at the other end through the neutral support position. The guide bodies 26, 26' extend/shrink the operation wires 6, 6' by the same length, thus a machine body is prevented from being inadvertently traveled.

Title: Three-dimension data input device
Inventor: UNUMA MUNETOSHI
IPC: G06F3/0354
Filed: 1987-07-24
Abstract: PURPOSE:To input a 3-dimension data by measuring an acceleration and gravity change caused when an object is moved by a pressure sensor and applying multiple integral to the acceleration to obtain a relative position and measuring a change in the gravity direction to detect the rotation of the object. CONSTITUTION:When a spherical shell 11 is in standstill, outputs of pressure sensors 13-15 are taken as the initial state. In case of moving the spherical shell 11, a negative pressure fluctuation is caused in the moving direction in the inside of the spherical shell in proportion to the acceleration and a positive pressure fluctuation is caused in the opposite direction. The pressure fluctuation is measured by the sensors 13-15 to send a sensor output 16 to an arithmetic processing section 17. The processing section 17 obtains the direction of acceleration and the quantity of acceleration of the spherical shell by the vector sum of the sensor outputs 16 by the processing section 17. In applying multiple integral with respect to time to them, the moving direction and distance of the spherical shell are obtained and the data is outputted from a 2-dimension data output section 18. Moreover, the rotation of the shell is obtained from the pressure fluctuation in the inner face of the shell due to the change in the gravity acceleration direction by the rotation of the spherical shell.

Title: Learning type motor-driven actuator speed fluctuation reducing method
Inventor: KURA SHUKAKU
IPC: G05B13/02
Filed: 1987-07-24
Abstract: PURPOSE:To reduce the speed fluctuation with inexpensive circuit constitution by providing a learning mechanism receiving a command signal or the like and outputting a speed correction value, operating the best linear prediction of speed fluctuation and correcting the speed command by the predicted speed fluctuation. CONSTITUTION:A learning mechanism 1 receives a command signal r(s) and a speed loop output xsi(s) to output a speed correction value w(s) to the input of speed loop. That is, a command r(s) is given to the servo mechanism and the speed correction v(k) is generated in the mechanism 1 as the control system is being operated. When a sampling point reaches (n-1)T>=lT, the mechanism 1 calculates and produces the best linear prediction v(n) of the speed correction value w(n)=-v(n) at the next sample time nT according to the procedure of the recurrent model. Then the value -v(n) is used as the speed correction value at the sample point (n) to correct the speed command of the servo mechanism and the speed correction value at the next sampling time to the time (n) is decided by the procedure of the recurrent model from the speed fluctuation before the point of time (n). Thus, the drive speed fluctuation is reduced with inexpensive constitution.
